The correct answer is: Rice.
Rice is the primary Kharif crop of Odisha. It is grown in the rainy season, from June to October. The main rice-growing areas in Odisha are the coastal districts of Puri, Cuttack, and Balasore. Rice is a staple food in Odisha and is used to make a variety of dishes, such as puri, dosa, and idli.
Wheat is a Rabi crop, which means it is grown in the winter season, from November to March. Wheat is not a major crop in Odisha.
Maize is a Kharif crop, but it is not as important as rice in Odisha. Maize is grown in the eastern and southern parts of the state.
Pulses are a group of crops that include beans, lentils, and peas. Pulses are a major source of protein in Odisha. They are grown in all parts of the state.
